UNITED STATES WILLIAM NEIL, OF CHICAGO, ILLINOIS, ASSIGNOR TO WM. NEILILLINOIS.

PATENT OFFICE POURING' SPOUT.

1 '1 '0 cZZ whom it may concern:

Be it known that 1, WILLIAM NEIL, a citizen. ofv the United. States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvementin Pouring Spouts, of whichthe following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

The invention relates to pouring spouts and particularly to that typewhich are provided with a means through which air is introduced into thereceptacle while pouring the material from the receptacle to therebyfacilitate draining of the receptacle.

The invention has as its prime object the provision of a constructionsuch as that above referred to having the air passage formed ofthe'material of which the spout is formed.

It is an additional feature of the invention to construct the spout ofsheet material and to form a part of the material with a 5 groove orrecess the latter being closed by a portion of the spout which overlapsthe grooved or recessed part to thereby form the passage whereby air isintroduced into the receptacle while the fluid is being drained from thereceptacle.

It is a further object to provide a construction such as above referredto with a tubular element which is inserted into the tubular passagethus formed, said element being provided for the purpose of insuring theintroduction of air into the receptacle without interference by thefluid being drained from the receptacle.

The invention will be explained in conjunction with the accompanyingdrawings which illustrate one embodiment of the invention, it beingobvious however that changes and modifications may be resorted towithout departing from the spirit of the appended claims forming a parthereof.

Referring to the drawings Fig. 1 is a central vertical section of aspout constructed according to one embodiment of the invention.

Fig. 2 is a section taken on the line 2-2 of F 1 looking in thedirection of the arrows.

Fig. 3 is a view similar to Fig. 1 showing a modified arrangement whichmay be employed, and

Fig. 4 is a bottom plan view of the structure illustrated in Fig. 3.

The embodiment of the invention illustrated in the drawings contemplatesa construction having a screw-threaded portion 10 whereby the device maybe detachably secured to a receptacle 11 from which the. fluid is to bedrained. The screw-threaded portion 10 has secured to it anannular'portion'll from which the spout-12 projects.

The material of which the spout 12 is formed is in the presentconstruction of -a suitable shaped sheet of material the. ads jacentedges 13 and 14 thereof overlapping each other so as to complete thetube, it being'of course understood that these edges are solderedtogether or otherwise secured so as to prevent opening at the seam thusformed. The edge 14 is provided with a channel shaped depression orrecess 15 which extends throughout substantially the entire length ofthe tubular spout portion 12. The portion 13 of the sheet overlaps theopening such as 16 of the channel shaped part and thus completes the airpassage whereby air is introduced into the interior of the receptacle 11during the pouring operation.

As illustrated in Figs. 1 and 3 the tubular passage may have a tubularextension such as 17 or 18 suitably secured thereto which may be eitherbent to form the goose neck as illustrated in Fig. 8 or provided withthe perforations 19 illustrated in Fig. 1. These latter tubular portions17 and 18 being provided for the purpose of at all times insuring theintroduction of air into the receptacle 11 during the pouring operationas it is manifest that as the liquid passes the open end of the U-shapedtubular element 17 that this passage of the liquid will draw air throughthe air passage of the spout and thereby facilitate pouring through saidspout.

From the foregoing description it is manifest that a spout is providedhaving a tubular passage which extends substantially throughout theentire length of the spout and provides means whereby air may beintroduced into the receptacle to thereby facilitate the pouring ordraining of the material from the receptacle.

It is further evident that the tubular passage is formed of the materialof which the spout is formed.

a '00., or CHICAGO" It is further manifest that by forming the passageby providing a recessed part which is closed by an overlapping portionof the materialforming the spout that an extremely simple and cheap yetefficient structure is provided for accomplishing the desired ends.

Having thus described the invention what I claim and desire to cover byLetters Patent is:

1. A spout formed of a sheet of material which is bent to form a tubethrough which liquid may be poured from a receptacle with which thespout is associated, said sheet being also formed to provide alongitudinally arranged air passage, one end of which opens into thatend of the tube from which the liquid is emitted to thereby cause anyliquid entering the passage to bedischarged through the discharge end ofsaid spout and a tubular element, one end of which is inserted into oneend of said passage and extends therefrom with its oppositeendterminating in spaced relation to a part of the spout to allow liquid topass over said last mentioned end of the tubularelement.

2. A spout formed of a sheet otmaterial which is bent to form a tubethrough which liquid may be poured from a receptacle With which thespout is associated, said sheet being also formed to provide alongitudinally arranged air passage one end of which opens into that endof the tube from which the liquid is emitted to thereby cause any liquidentering the passage to be discharged through the discharge end of saidspout and a U-shaped tubular element extending from one end of saidpassage toward the interior of the receptacle and having an end whichterminates adjacent and in spaced relation to a portion of the spout toallow liquid to-pass over said last mentioned end of said tubularelement.

In witness whereof, I hereunto subscribe my name this 6th day of June A.1)., 192a.

VI'LLIAM NEIL.
